Abstract
La présente invention a trait à un dispositif de communication sans fil mobile, qui comprend une carte imprimée portée par un logement et disposant d'un circuit RF et d'un processeur opérant avec le circuit RF. Un clavier est porté par le logement et comprend un circuit de clavier. Un connecteur de clavier est porté par le clavier et relié de manière opérationnelle au circuit RF et au processeur. Plusieurs lignes de raccordement Sortie touche et Entrée touche relient le connecteur du clavier au circuit du clavier. Les filtres portés par le clavier sont reliés à chaque ligne de raccordement Sortie touche et Entrée touche pour réduire l'énergie RF extraite de l'antenne ou de l'interférence externe et interférant avec le fonctionnement normal du processeur.
